【摘要】太原基准地震台数字化形变观测仪器伸缩仪和体应变仪记录的分钟值固体潮曲线上叠加有锯齿状的高频干扰,为探寻干扰源,对附近的抽水井、高压输电线、溶洞及煤矿进行调查分析,发现其对观测仪器的影响均不明显,认为与山洞下面可能存在的裂隙带有关。更多还原

【Abstract】 The high-frequency interference in zigzag is found super-positing on minute-value curve of solid tide recorded by body strain and extensometer of digital deformation at Taiyuan Reference Seismological Station.In order to find out the interference source,the investigations on nearby pumping wells,high voltage transmission lines,karst caves and coal mines were carried out.It is found that the influences of all these factors are unobvious.It is guessed that the interference probably has something to do with the fractures at the bottom of the cave.更多还原
